SYSTEM DESCRIPTION
The Shure UHF Wireless microphone system is a frequency-agile diversity sys-
temoperatingintheUHFband.Boththereceiverandthetransmitteraresynthesizer
controlled via Phase Locked Loop (PLL) circuitry for clear, steady radio frequency
(RF)signal.Thereceiverisavailableineitherdualorsinglemodelsthatfitintoastan-
dard 19 inch (482 mm) equipment rack. An auxiliary unswitched AC output jack al-
lowsmultiple receivers to belinked “daisy chain” style. The optional UA830 Remote
AntennaKitscan bepoweredby12Vdc,500mAoutputprovidedthroughtheanten-
na connectors. The optional UA840 Antenna Distribution Amplifier Kits allows con-
nection of multiple receivers using only two antennas.
SYSTEM FEATURES
Shure UHF Wireless Systems offer many exceptional features, including:
•Frequency Agility. The operating frequency of transmitters and receivers can be
easily switched to any setting in the UHF range. Settings are available in pre-pro-
grammed incremental steps that allow for necessary channel separation.
•Menu Driven Display. User–programmable receiver display shows Group,
Channel, Frequency, Name, Squelch level, and Locked/Unlocked status.
•Exclusive Shure MARCADCircuitry. MARCAD (MAximum Ratio Combining
Audio Diversity) circuitry constantly monitors signals from both receiver sections
and combines them in a single output signal.MARCAD providessuperior recep-
tion and exceptional freedom from dropouts.
•NoiseSquelch Circuitry. Analyzessignal quality insteadofsignal strength .This
virtually eliminates the possibility of annoying noise bursts coming through your
receiver.
•Dual RFLevel Meters. TheU4Sand U4D receivers have two RF meters, one for
eachantenna.Thedualmetersindicatereceivedsignalstrengthateachantenna,
and make it easier to identify and troubleshoot “dead spots.”
•AudioMetering. Each receiver includes a seven–segment audio meter that lets
you monitor audio level and helps optimize transmitter gain setting.
•TransmitterDisplay.ShowsGroup,Channel,BatteryPowerLevel,andPOWER
LOCK ON/OFF* condition. Both displays are user programmable.
•TransmitterBattery Power Meters: Meters on the transmitter and the RECEIV-
ER MONITOR TRANSMITTER BATTERY POWER LEVEL from the receiver as
well as from the transmitter.
•ToneKey Squelch: Eliminatesunwantednoisefromenteringsystem;eliminates
popping noises when turning the transmitter on or off.
•Dual Receiver Option: Provides greater flexibility while conserving rack space.
•PreconfiguredGroup/Channel: Ensures frequency compatibility and simplifies
system installation.
•Network Expansion Capability.U4S and U4D receivers have a 25–pin serial con-
nector for future computer control and monitoring via an accessory interface box.
•DC/DC Converter: Ensures consistent audio and RF performance, even if bat-
tery voltages change.

Installing Rear Mounted Receiver Antennas
Attach the supplied UHF antennas to the antenna BNC connectors on the receiver
back panel, as shown in Figure 5. For best performance, orient the antennas with tips
pointing away from each other at a 45°angle from vertical.

power source.
NOTE: If the receiver is rack-mounted, or if front–mounted antennas are used,
the antennas should extend above the rack cabinet or be remotely located. Im-
proved diversity performance may be obtained by installing one or both antennas
at a remote location and separatingthem by 1.5 meters(60 inches) or more. An-
tennas at remote locations should be connected to the receiver via UA825 or
UA850 Extension Cable Kit(s) or other suitable low-loss cable (RG8 or equiva-
lent) and used in conjunction with a UA830 Active Remote Antenna Kit.
VIEWING CURRENT RECEIVER SETTINGS
To view current settings on the receiver display, proceed as follows:
1. Turn the receiver on by pressing upper half of the POWER switch.
2. Press either the “+” button or the “–” button on the receiver front panel to scroll
through the current settings.
PROGRAMMING THE RECEIVER
You can change the receiver Group/Channel setting, the operating frequency,
squelch level, and receiver name through the programmable display. The display
can then be locked to prevent accidental changes. Instructions for programming
each display function are presented in the following paragraphs.
Changing Receiver Group/Channel Settings
The receiver display identifies frequencies by Group and Channel. This allows
convenient setup of compatible systems. A complete list of compatible frequency
Groups and Channels is included in the separate UHF Frequency Compatibility
Guide. To change the receiver Group and Channel settings, proceed as follows:
1. Turn the receiver on by pressing upper half of the POWER switch.
2. Press the MENU button. The “+ MENU –” display will appear, as shown in Figure
